Definitions
- the present invention is in the field of armor against regular and armor piercing firearm projectiles and their fragments, and aims at providing lightweight armor suitable for a variety of purposes such as, for example, for making protective garments, for fitting enclosures with opaque or transparent armored wall portions and the like.
- the invention is based on the surprising observation that if a slanting body of a lightweight material is put in the path of a firearm projectile, the latter is subjected to asymmetric forces which cause the projectile to be diverted from its trajectory in the direction of the obtuse angle formed between the trajectory and the body.
- the projectile may also be broken up, and all this has the result that the projectile can easily be stopped either by the said body or by another body of lightweight material.
- a lightweight armor assembly resistant against the penetration of firearm projectiles comprising at least one front body of a lightweight material slanted relative the expected trajectory of an oncoming firearm projectile, and a rear body.
- the armor assembly according to the invention may comprise two or more front bodies.
- the lightweight material used in accordance with the present invention may be transparent or opaque and be either soft or hard. Where out of the two complementary angles formed between the trajectory of the firearm projectile and the surface of said at least one front body the upper angle is obtuse and the lower one is acute, the impinging firearm projectile is deflected upward. In contrast, where the lower angle is obtuse and the upper one is acute, an impinging firearm projectile is deflected downward.
- a transparent front body may be made of any suitable inorganic or organic transparent material such as glass, glass ceramics, PMMA (perspex), various synthetic materials such as polycarbonates, epoxy resins, PVC and the like.
- An opaque front body may be made of any suitable lightweight material. If desired, the opaque front body may be made of a heavy duty cloth material such as of KevlarTM, SpectraTM, and various epoxy materials and the like. Such materials may be used in soft pliable form or in composite hardened form, e.g. by being soaked with a suitable polymeric material which hardens upon curing.
- the front body in the lightweight armor assembly according to the invention may be a monoblock, i.e. be made of a single material. Alternatively, it may be laminated and made of two or more layers of the same material or be composite and be made of two or more layers of different materials. In either case adjacent layers are suitably glued or cemented to each other.
- the individual layers may be slanted relative to the expected trajectory of an oncoming firearm projectile.
- an oncoming firearm projectile penetrates across the said at least one front body and when it emerges therefrom, either intact or broken up, it is deflected either upwards or downwards depending on the slant of the front body relative to the trajectory, and does not penetrate across the rear body. In case of a thick front body the projectile may be deflected without hitting at all the rear body.
- the required impact resistance of the rear body is much less than in the prior art.
- its weight per unit area may be about half of that of a prior art body which has to be resistant to the full impact of an oncoming firearm projectile.
- FIG. 1 there is shown schematically an assembly comprising a slanted lightweight front panel 1 and a vertical rear panel 2 .
- Arrow 3 stands for an oncoming firearm projectile and as can easily be concluded from the figure, the trajectory of the projectile 3 is essentially normal to the vertical rear panel and of the two angles formed at the intersection of the trajectory of projectile 3 with panel 1 , the upper angle is obtuse.
- the projectile 3 once the projectile 3 has penetrated across panel 1 it is diverted upwards as shown at 4 , either as a whole or broken up, and it either does not at all hit the vertical rear panel 2 , or else is readily intercepted by it without passing across.
- Fig. 3 which is essentially similar to that in Fig. 1 with similar components again being marked by the same numerals, panel 1 is sheathed by sheets 8 and 9 of a different lightweight material. Basically this embodiment operates in a similar way as the embodiment of Fig. 1.
- the embodiment shown schematically in Fig. 4 comprises a front panel 10 , a lightweight material block 11 composed of a plurality of slanting plates 12 glued or cemented together, and a vertical rear panel 13 .
- the firearm projectile 3 is diverted by any of the plates 12 which it hits on its way, and it accordingly does not penetrate the rear panel 13 .
- the lightweight front and rear panels may be transparent or opaque, according to requirements.
